This article describes a remarkably rich fauna of freshwater prosobranchs endemic to the French Pyrenees, which comprises three new (sub)species, viz. Moitessieria nezi spec. nov., Palaospeum bessoni rebenacqensis subspec. nov. and (?)P. nanum spec. nov., and Alzoniella junqua Boeters, 2000. These four endemic species can be found sympatric with two species of Bythinella which have a larger distribution in the Pyrenees.
